The ISO disc images associated with each Proceedings of the Integrated Ocean Drilling Program volume are optical disc archive files that contain expedition reports and other content distributed at the time of initial publication. The ISO disc image for each Proceedings volume is a hybrid Macintosh/Windows ISO 9660 image. Users may download and burn the ISO file to a blank DVD-R disc or mount a disc image to emulate a disc. Consult your operating system’s documentation for specific instructions. Third-party utilities are available to assist with the process.
